Well, half my lower jaw is. Dentist today, for a temporary crown to get rid of a cavity. Got nitrous oxide, so I had a nice nap after I got home. Woke an hour ago, and my jaw is still numb. No dinner for me yet. I don’t wish to end up having eaten my tongue.
Getting out of the chair, I asked the assistant, “Did I talk about mathematics?” (While I was under the nitrous, that is.)
“No.” Quizzical but tolerant look.
“Good.”
Would I have talked about abstract algebra, or basic topology? I could probably ramble on much longer about the topology. Compact spaces appeal to me when under anesthesia.
